01Setup

One command.
That’s the setup.

It installs the Claude Code CLI plus Git and Node.js (our setup and hire skills run on Node), then checks that the result actually works. Copy the line for your computer, paste it into the terminal, press Enter.

Before you start
  • A paid Claude plan (Pro or higher). Free accounts cannot sign in to Claude Code.
  • Your laptop’s admin password. The installer may ask for it once.
  • Laptop charged, charger with you.
  • On a Mac, allow ten minutes: Apple may download its developer tools first.
Mac · or Linux
Open Terminal: press ⌘ Space, type "Terminal", press Enter
$ curl -fsSL https://raw.githubusercontent.com/jtlgrowth/claude-code-installer/main/install.sh | bash
Windows · PowerShell
Open PowerShell: press the Windows key, type "PowerShell", press Enter
> irm https://raw.githubusercontent.com/jtlgrowth/claude-code-installer/main/install.ps1 | iex
Windows · Command Prompt
Use this one if the window says "Command Prompt" or "cmd", or if the line above turned red
> powershell -NoProfile -ExecutionPolicy Bypass -Command "irm https://raw.githubusercontent.com/jtlgrowth/claude-code-installer/main/install.ps1 | iex"
02Then

Six steps and it’s yours.

  1. Close the terminal and open a new one. Not optional: the new window is what picks up what was just installed. On Windows, PowerShell or Command Prompt both work from here.
  2. Check Node: type node --version and press Enter. It should say v20 or higher. Anything else: the fix is one line.
  3. Type claude and press Enter.
  4. Type /login and sign in. Claude Code is running.
  5. Get the skills: open jtlgrowth.com/skills, enter the access code from the room, run the line for your computer.
  6. Name it: open a new window, type claude, then /setup. It asks four questions. The last one is the word you type to open it, like ana. From then on: new window, type ana, press Enter.
03If it doesn’t work

Seven things go wrong. All seven are quick.

claude: command not found or 'claude' is not recognized

You’re in the terminal window you had open before installing. Close it, open a new one, try again. Still there on Windows? Run the install line once more (it saves the path for new windows), then open a new window.

node is not recognized, not found, or older than v20

Open a new window first: the install may have just put it there. Still missing? Paste one line, then open a new window and check node --version again.

Windows PowerShell or Command Prompt: winget install OpenJS.NodeJS.LTS

Mac brew install node

No winget or no Homebrew: download the LTS installer from nodejs.org, run it, open a new window.

Windows says 'irm' is not recognized

You are in Command Prompt, not PowerShell. Windows Terminal opens whichever one is set as your default. Use the Command Prompt box above instead. It runs the same install, and it works in both windows.

Windows says running scripts is disabled

Paste Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass first, press Enter, then paste the install command again. It applies to that one window only. The Command Prompt box above already includes this.

Mac: a popup asks to install the Command Line Tools

Click Install and wait for it to finish (a few minutes on event wifi). Then paste the install line again. It picks up where it stopped.

It asks for a password and nothing shows when you type

That is normal: the terminal hides passwords. Type your laptop login password and press Enter.

Typing your name (like ana) does nothing

Open a new window. The name works in Terminal, PowerShell and Command Prompt, but only in windows opened after /setup finished. On Windows, closing it with Ctrl+C may ask Terminate batch job (Y/N)?: type Y, nothing is lost.

Anything else: the full manual walkthrough, every step separately, is here. Or send us the last 20 lines of the output at hello@jtlgrowth.com. The error text is the useful part, a screenshot of the whole window isn’t.

04What you just ran

Nothing hidden.

The script is open source, MIT, and short enough to read before you run it: the installer. It doesn’t download Claude Code itself. It calls Anthropic’s own installer, which fetches a checksum-verified binary. Running the command again later is safe: it updates what’s out of date and leaves everything you’ve set up alone.
